Okay, I'll be prepared to be flamed.
I saw nothing wrong with the video. I took a course similar to this. It included all the barrier cover / concealment shooting, as well as a drill having someone standing in front of you. In my case the drill was to use your weak arm to "sweep" the person out of your way and behind you while you draw from the holster, put two in the target with a one-handed shot as you sweep your partner back (they had to be behind you before you start to draw), then go to a standard two-handed form for the follow ups. The drill was closely supervised and I felt it was quite safe. The course instructor billed the drill as getting a loved one out of the way and behind you to engage a street mugger or robber or whatever.
My course (which was intermediate, and this one looked advanced), while covering light use (non-mounted), only did so in daylight, and we didn't do any vehicle exercises. Frankly, I like that they did that here. If I had to evaluate the two likeliest scenarios where I might need to use a pistol, it would be at night (home invasion) and in my vehicle (carjacking or similar and I can't use the car to get away). Watching the video actually is making me want to find a course where I could practice vehicle situations, especially accessing my pistol since I am always trying to figure out the whole leaving it in the holster versus putting it somewhere else in the vehicle thing. Not to mention the limited movement being belted in allows.
